Question 1080590
.
How It can be a real curve in polar coordinate while "r" produced by the formula is negative for any and for all {{{theta}}} ?


This formula represents NO real curve in polar coordinate.


In other words, the formula does not represent any real curve in polar coordinate.
It even does not represent any SINGLE POINT in polar coordinate.
It represents NOTHING, except of author's total/absolute incompetency in the subject.


The reference to another site is not convincing/persuasive.
